There is a line that includes the points (8, 5) and has a slope of 0. what
is the equation in slope
slop -intercept form?

y=5

Step-by-step explanation:

Slope intercept form: y=mx+b

You know that the slope is 0, and that the line passes through (8,5). So you plug in 0 for m and (8,5) for x and y

Therefore:

5=(0)(8)+b

5=0+b

5=b

Now that you know what b is, create your equation using m and b.

y=mx+b

y=0x+5

y=5

Done!

There is also a clever trick when any line with a slope of 0 is a y=_ equation. Since you know it passes through a point where the y-coordinate is 5, you can immediately figure out that the equation is y=5.

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
